AP Racing CP2623-91PRM115 0.700″ Master Cylinder, Forged Alloy, Metric M8x1.25 pushrod

Only one in stock! CP2623-91PRM115 AP Racing remote master cylinder, new in the bag. 115mm push rod length with METRIC M8x1.25 threads. 0.700″ bore. Mounts the same as any other CP2623 master cylinder, but the metric pushrod threads are a bit unusual in the U.S., so we are selling this one that we have in stock at a discount. If more are needed, we can always special order from AP in the U.K.

The AP Racing CP2623 is a lightweight, compact, forged-bodied master cylinder suitable for all brake and clutch applications — especially where installation space is restricted. The forged aluminium alloy body saves 50g over the equivalent cast version, and the short travel to cut-off gives crisp, immediate pedal response.

Features

• Forged aluminium alloy body
• 50g weight saving over the cast version
